Walls are created from series of polygons. You can add image based textures to different wall faces thus creating an interior and exterior look. Image based textures on walls may show a repeat pattern or seams.
It is also beneficial to use shaders as textures for walls. By using shaders that take on the color of the wall you can produce realistic coloring. A shader does not show any seams like a tiled image based texture might. Zooming in is clearer when shaders are used.
It is a good idea to assign a texture for the class of your walls. That way you do not have to texture each wall individually.
To Apply a Texture to a Single Wall
1. Select the desired wall or walls.2. Click the Texture Tab on the Object info palette.
If expand is not selected, the mapping chosen is applied to all wall faces.
A preview and Edit Mapping button is listed for each exposed surface of the wall.
4. Select the texture for each wall side.
5. Execute steps 4-11 in To "apply an image based texture to an object" for each wall face to which you want to apply a texture, or execute steps 4-7 in To "apply a shader texture to an object" for each wall face to which you want to apply a texture.
